Volcanoes have been erupting on the earth for millions of years. More than five hundred of them still erupt today. These are called active volcanoes. Volcanoes are located in belts or chains. They are found where the earth’s crust is weak. The weak spots let the hot rock escape when the volcano erupts.

Many volcano belts are mountain ranges along the edges of continents. One belt runs along the western coast of South America up through the western part of the United States. Other volcanoes are found in ocean basins.

About three-fifths of all active volcanoes in the world are in the Pacific Ocean. Many of these volcanoes erupt under the water. The Hawaiian Islands were built by volcanoes that began erupting under water and finally reached the surface of the ocean.

Read the following passage, and answer the questions that follow

On April 30, 2018 the Pu’u ‘O’o crater on Hawaii’s Kilauea volcano, suddenly collapsed. It was the starting point for the volcano’s months long eruption, which went on to produce 320,000 Olympic-sized swimming pools’ worth of lava that transformed the landscape and ultimately destroyed 700 homes.

A volcanic eruption occurs when hot materials from the Earth's interior are thrown out of a volcano. Some eruptions are terrible explosions that throw out huge amounts of rock and volcanic ash and can kill many people. Some are quiet outflows of hot lava. Several more complex types of volcanic eruptions have been described by volcanologists. These are often named after famous volcanoes where that type of eruption has been seen. Some volcanoes may show only one type of eruption during a period of activity, while others may show a range of types in a series.

Do all volcanoes display only one type of eruption during a period of activity?
